摘要
本文以塔中四一轮南沙漠管线工程为实例，介绍了补回材料一热收缩套的结构、现、格．详述了现场补口施工工艺过程．并强调了在沙漠环境下热收缩套补口施工的注意事项。与用石油沥青补口相比，用收缩套补口具有操作简单、劳动强度低和补口质量易于保证等优点。
This articl introduces the field joint coating technology of heat shrink sleeve in desert envi-ronment and the specification and the structue characteristic of heat shrink sleeve, taking thedesert pipeline form Ta Zhong 4 to Lun Nan as a practicaI example. The technique ls not only easyto guarantee the quality, but also to reduce the labour strength as in comparison with the fieldjoint coating of petroleum asphalt.
